There're two ways to deal with image file. Burn it & you shall have an actual disc. This way you need to have a blank DVD disc. Mount it & you shall have a virtual disc. This way you don't need to have a blank disc. It will act like an actual disc and is a great way to view image file right from your computer.

Now there's two popular image file types for JAV. ISO file & MDS file (the one where you see I00, I01 etc. files in the folder)

To burn these two image file type. ImgBurn is a great program to handle both of them. It's small, easy-to-use, and best of all. free of charge.
Nero can burn ISO just as well but can have problems with MDS.

To mount it, i.e. to make it appears as a DVD disc in your system without having to burn it. Daemon Tools lite version is also a small and free program. It can handle both file type very well. Alcohol 120% is also a great program to mount these two files.
For ISO only, Virtual CloneDrive is a small program designed specifically to mount DVD ISO file. It's really great program. Unfortunately it can not mount MDS file.
